Further French travel disruption is expected this week with a nationwide air traffic controllers strike on Thursday and Friday.
This follows a second wildcat strike which shut the port of Calais for the second time in a week.
The situation is likely to be compounded with a forecast of “unusually high temperatures” in France from tomorrow, according to the Foreign and Commonwealth Office.
MyFerryLink staff walked out yesterday over the sale of its ferries to rival DFDS, affecting all Dover to Calais ferry services in action which could continue until Thursday, according to latest reports.
The Eurotunnel-owned former SeaFrance ferry company is due to cease operations on Thursday following the sale of its ferries.
The FCO said: “There is ongoing industrial action causing disruption to cross-Channel services into the port of Calais.
“The port of Calais is closed, with resulting queues. Check online with your chosen operator and plan your journey to avoid disruption.
“Air traffic controllers across France are planning a nationwide strike on Thursday and Friday. Please contact your airline for the status of your flight.”
